RECEPTOR FOR WIND TURBINE BLADE LIGHTNING PROTECTION

摘要

A receptor assembly for lightning protection of an object, such as a wind turbine blade, includes a receptor disk configured to be placed on a surface of the object, a receptor block insulator with an integral receptor block, a cover that engages the receptor block insulator, and a cap that engages the cover. The receptor disk and the receptor block may be made of electrically conductive materials, and the cover, and the cap, and the receptor block insulator may define a chamber among them that is lined with an electrically-conductive coating sandwiched between relatively high dielectric media to electrically isolate and shield internal parts of the receptor assembly from receiving a lightning strike directly.
